鲫孔穴病的病原诊断及防治技术

Studies on the Pathogen Diagnosis and Control of Perforation Disease in Carassius auratus

对发生于2007年的鲫(Carassius auratus)孔穴病的病原进行分离、鉴定及药敏试验,并同时开展了该病的防治试验。结果表明,病原为嗜水气单胞菌,药敏试验显示该菌对硫酸新霉素、卡那霉素、庆大霉素高度敏感,通过在水体施用二氧化氯0.5g/m3,在饲料中拌加庆大霉素药饵,连续投喂3d,7d后病鱼停止死亡,15d后恢复正常。

A pathogen, isolated from the perforation disease in Carassius auratus was identified as Aeromonas hydrophila in 2007. The results of drug sensitive test showed that , among 10 antibiotics, Neomycin Sulfate, Kanamycin, Gentamicin had the most inhibitive effect on the pathgeon. Through spilling chlorine dioxide 0.5 g/m^3 in water and feeding with adding Gentamicin for 3 days,the sick fish dying stoped after 7 days. the fish recovered after 15 days.
